Manufacturing Process
A smooth core tube is inserted into an aluminum sleeve and then the fins are extruded out of the aluminum sleeve.
Fins Type:
The fins are solid plain or serrated into segments or as your design.
Unfinned Section
Both plain ends with appr. 10mm~50mm and gaps (Unfinned Section) in the middle.
Surface Coating
Both bare ends of Bimetallic Finned Tubes shall be Zinc or Aluminum that metallized applied by an electro spray arc system coating.
Accessories
Tube Support Box, Clamp or Spacer Box(Materials: Aluminum, Zinc or Stainless Steel).
Applications:
The common application fileds are:

  1. Heat exchangers units for power plant(electric, nuclear, thermal and geothermal power plants);
  2. High corrosive systems (condensers, evaporators, sea water desalinations, fertilizing, urea systems, ammonia, gas, corrosive acids);
  3. The petroleum, chemical and petrochemical industries;
  4. The food processing and refrigeration industries;
  5. Natural gas treatment;
